El “Contubernio” de Munich

2002

Se trata de una carta al director que enviada a "El País" en protesta por cómo se ha llevado a cabo la celebración del 40 aniversario del Contubernio de Múnich en el Centro de Estudios Políticos y Constitucionales. Se desconoce si finalmente fue publicada.

¡Los de Múnich, a la horca!

Long-term no-tillage application increases soil organic carbon, nitrous oxide emissions and faba bean (Vicia faba L.) yields under rain-fed Mediterra…

2018

The introduction of legumes into crop sequences and the reduction of tillage intensity are both proposed as agronomic practices to mitigate the soil degradation and negative impact of agriculture on the environment. However, the joint effects of these practices on nitrous oxide (NO) and ammonia (NH) emissions from soil remain unclear, particularly concerning semiarid Mediterranean areas. In the frame of a long-term field experiment (23 years), a 2-year study was performed on the faba bean (Vicia faba L.) to evaluate the effects of the long-term use of no tillage (NT) compared to conventional tillage (CT) on yield and NO and NH emissions from a Vertisol in a semiarid Mediterranean environmen…

Effects of arbuscular mycorrhizal symbiosis on growth and N2 fixation of Trifolium alexandrinum under late drought stress conditions.

2010

Several experiments, mostly carried out under controlled conditions, have shown that arbuscular mycorrhizal (AM) symbiosis enhances nutrient uptake and improves drought tolerance of host plants. The present research, carried out in a typical Mediterranean environment, evaluated the effect of AM symbiosis on berseem clover (Trifolium alexandrinum L.) grown in the field under both late drought stress and well-watered conditions. The crop was subjected to repeated defoliation. N2 fixation was estimated using the 15N dilution method and using ryegrass (Lolium multiflorum var. Westervoldicum) as the reference crop. In late drought conditions, AM symbiosis resulted in a significant increase in bi…

Militarization of Security Policies in Central and Eastern Europe

2023

Pawłuszko explains the process of militarization of security policies in the CEE region since the Crimea Crisis. According to the Copenhagen School, he focuses on reconstruction of the Central-Eastern European Security Complex and draws attention to the changes in military policies of states in the region. Pawłuszko explores theoretical implications, as well as practical consequences of the NATO-Russia rivalry on the “eastern flank” of Europe. The chapter concludes with a study of perspectives on geopolitical agenda of the CEE region.

Morpho-agronomic and genetic diversity among twelve sicilian agro-ecotypes of lentil (Lens culinaris)

2015

Although Sicily is relatively small (about 25000 km2), it accounts for several agro-ecotypes of lentil (Lens culinaris Medik.), for many of which no data on morphological, agronomic, and organoleptic characteristics are available to date. Thus, experiments were performed to characterize 12 lentil agro-ecotypes from different areas of Sicily, including some small islands surrounding the main island, and to assess the extent of genetic diversity (by means of six inter-simple sequence repeat [ISSR] primers). A famous agro-ecotype from central Italy (Castelluccio di Norcia) and two commercial varieties from Canada (Eston and Laird) were also included in the study. The results showed a large deg…

Nitrogen input effectiveness on carbon sequestration in rainfed cropping system

2016

The combined effect of total N and C/N ratio had a large influence on the decomposition rate and consequently on potential soil organic carbon sequestration. The aim of the work was to evaluate Carbon sequestration potentiality under three mineral N fertilization levels in interaction with two cropping systems characterized by addition of N input due to leguminous species in the rotation. The study was carried out in the semiarid Mediterranean environment in a 18years long-term experiment. Is well know that in the semiarid environment the excess of N fertilization reduces biomass yield and the consequent C input. On the contrary, both N and C input determine high difference in C/N input rat…
